The Mariners claimed Loutos off waivers from the Washington Nationals on Thursday.
Loutos, a 26-year-old right-hander, made 12 MLB appearances during the 2025 season, split between stints with the Dodgers and Nationals. He posted a 12.75 ERA and a 2.33 WHIP with an 8:8 K:BB over 12 innings. He fared significantly better with the Nationals' Triple-A affiliate in Rochester, posting a 4.32 ERA and a 27:13 K:BB across 25 innings. He'll join the Mariners' 40-man roster.

Rotowire
The Mariners acquired Wilcox from the Rays on Wednesday in exchange for cash considerations.
Wilcox had been designated for assignment by the Rays earlier this week and will now join a new 40-man roster. The 26-year-old spent most of the 2025 season at Triple-A Durham, holding a 3.71 ERA and 57:24 K:BB over 51 innings. It was his first year as a full-time reliever, and Wilcox is likely to begin the 2026 campaign in the bullpen at Triple-A Tacoma.

Mariners' Andres Munoz: Club option for 2026 exercised
Rotowire
The Mariners exercised Munoz's $6 million option for 2026, Francys Romero of BeisbolFR.com reports.
Munoz saved 38 regular-season games while posting a 1.73 ERA and 83:28 K:BB over 62.1 innings, so the Mariners made the easy decision to retain him at a bargain rate in 2026. The club also has an $8 million option for 2027 and $10 million option for 2028 on Munoz. The hard-throwing reliever should be one of the best closers in baseball again next season.
Mariners' Bryce Miller: Could receive injection for elbow
Rotowire
Miller will have a follow-up appointment soon with Dr. Keith Meister to determine the next steps for treatment of a small bone spur in his right elbow, Adam Jude of the Seattle Times reports.
Miller received a platelet-rich plasma injection in early June after being diagnosed with a bone spur in his pitching elbow. He returned in August and was healthy for the rest of the regular season and playoffs, saying "the best I felt all year" was at the end of the season. Miller is not expected to require surgery, but he could be given a cortisone injection during his follow-up appointment and perhaps an additional one at the start of spring training. The 27-year-old had a disappointing regular season for the Mariners, posting a 5.68 ERA and 74:34 K:BB over 90.1 innings covering 18 starts.
Mariners' Colt Emerson: Will compete for Opening Day spot
Rotowire
The Mariners are expected to give Emerson "runway" to win an Opening Day roster spot, Adam Jude of the Seattle Times reports.
Most of Emerson's playing time in the minors has come at shortstop, but he's also played some second base and third base. With Eugenio Suarez entering free agency, the hot corner appears the most likely path for Emerson, who is expected to compete with Ben Williamson for the starting job. Emerson is just 20 and has only six games of experience at Triple-A Tacoma, but Jude notes that the Mariners considered putting Emerson on their playoff roster taxi squad. The left-handed hitter slashed .285/.383/.458 with 16 home runs and 14 stolen bases over 130 games across three levels in the minors in 2025.
Kirby didn't factor into the decision during Monday's 4-3 loss in Game 7 of the American League Championship Series against the Blue Jays, allowing one run on four hits and one walk while striking out three over four innings.
Kirby was tagged for a run in the bottom of the first inning after issuing a leadoff walk, followed by a pair of singles. However, he was able to escape the jam without suffering further damage and exited the matchup with a lead. The Mariners would later surrender a two-run lead in the seventh, bringing the right-hander's postseason run to an end. Kirby responded nicely from a disastrous outing in Game 3, when he surrendered eight runs on eight hits and two walks while striking out four in four-plus frames.
